I have an existing part saved only as an STL mesh and I need it converted into a clean, watertight solid that I can use directly in engineering analysis software (ANSYS, SolidWorks Simulation, Abaqus, etc.). The STL must become a true parametric model—STEP Key points • Start from my supplied STL. • Re-surface or re-build so the file opens as a solid body, not a mesh. • Preserve every dimension and detail; no simplification unless we discuss it first. • Deliver the final file ready for import into FEA software without further repair. Please let me know which CAD platform you prefer and roughly how long you’ll need once you see the mesh. If you have past examples of mesh-to-solid conversions for analysis, feel free to share a screenshot or two to speed up selection.

I won’t simply wrap or auto-convert the STL and call it a STEP — for FEA use, the model needs to become clean solid geometry that imports without mesh-related errors. I work in Fusion 360 and can rebuild/re-surface your supplied STL while preserving the original dimensions and important details, then verify that the final body is closed, watertight and suitable for engineering analysis software such as ANSYS, SolidWorks Simulation or Abaqus. My workflow will be: • Inspect and repair the source mesh • Reconstruct the geometry as proper solid/B-Rep surfaces • Preserve dimensions and features without unnecessary simplification • Check the final solid for gaps/intersections • Deliver clean STEP + editable Fusion 360 source file if required Send me the STL/OBJ and I can review the mesh complexity first and confirm the most efficient rebuild approach.

Hi, I can convert your STL/OBJ mesh into a clean, watertight solid STEP model suitable for ANSYS, SolidWorks Simulation, Abaqus, and other FEA workflows. My approach will be to inspect the mesh first, repair geometry if needed, then re-surface or rebuild the part into proper CAD geometry rather than simply wrapping the mesh. I can handle: • STL/OBJ mesh inspection and cleanup • Hole/non-manifold repair • Surface reconstruction • Solid-body conversion • Parametric feature rebuilding where geometry allows • Preservation of dimensions and important details • STEP export • Solid-body verification • Import check for SolidWorks/FEA software • Minor revisions after your review I prefer SolidWorks for this type of reverse-engineering work, with additional mesh tools where useful. Turnaround is typically 1–3 days depending on mesh complexity, polygon count, and the number of organic/freeform surfaces. Please share the STL/OBJ file. I can review the geometry first and confirm whether it can be rebuilt directly or requires more extensive surface reconstruction. Best regards Ankit
